Hi minky

Logs look good.

All viruses are in system restore and inactive.

I give you later instructions how to empty it.

Other than that, any problems left?

Hi Shaba

Thank you for your response.

As far as I am aware there are no other problems.

Avast antivirus picked up those mentioned in the logs.

Thanks for your help

Hi

Then you're clean!

Now that you are clean, please follow these simple steps in order to keep your computer clean and secure:

Open HijackThis, click do a system scan only and checkmark this:

O2 - BHO: (no name) - {7E853D72-626A-48EC-A868-BA8D5E23E045} - (no file)

Close all windows including browser and press fix checked.

Looking over your log, it seems you don't have any evidence of a third party firewall.

As the term conveys, a firewall is an extra layer of security installed onto computers, which restricts access to systems from the outside world. Firewalls protect against hackers and malicious intruders. I want you to download a free firewall NOW from one of these excellent vendors:

1) Comodo (http://www.personalfirewall.comodo.com/)
2) Sunbelt/Kerio (http://www.sunbelt-software.com/Kerio-Download.cfm)
3) Agnitum (http://www.agnitum.com/products/outpostfree/download.php)
4) ZoneAlarm (http://www.zonelabs.com/store/content/catalog/products/sku_list_za.jsp?dc=12bms&ctry=US&lang=en&lid=nav_za)

If you are using the built-in Windows XP firewall, it is not recommended as it does not block outgoing connections. This means that any malware on your computer is free to "phone home" for more instructions. Simply put, Windows XP contains a mediocre firewall. This firewall is NO replacement for a dedicated software solution. Remember to use only one firewall at the same time.

Disable and Enable System Restore. - If you are using Windows XP then you should disable and re-enable system restore to make sure there are no infected files found in a restore point.

You can find instructions on how to enable and re-enable system restore here:

Windows XP System Restore Guide (http://www.bleepingcomputer.com/forums/tutorial56.html)

Re-enable system restore with instructions from tutorial above

Make your Internet Explorer more secure - This can be done by following these simple instructions:
From within Internet Explorer click on the Tools menu and then click on Options.
Click once on the Security tab
Click once on the Internet icon so it becomes highlighted.
Click once on the Custom Level button.
Change the Download signed ActiveX controls to Prompt

Change the Download unsigned ActiveX controls to Disable

Change the Initialize and script ActiveX controls not marked as safe to Disable

Change the Installation of desktop items to Prompt

Change the Launching programs and files in an IFRAME to Prompt

Change the Navigate sub-frames across different domains to Prompt

When all these settings have been made, click on the OK button.

If it prompts you as to whether or not you want to save the settings, press the Yes button.
Next press the Apply button and then the OK to exit the Internet Properties page.

Update your AntiVirus Software - It is imperitive that you update your Antivirus software at least once a week (Even more if you wish). If you do not update your antivirus software then it will not be able to catch any of the new variants that may come out.

Visit Microsoft's Windows Update Site Frequently - It is important that you visit http://www.windowsupdate.com (http://www.windowsupdate.com) regularly. This will ensure your computer has always the latest security updates available installed on your computer. If there are new updates to install, install them immediately, reboot your computer, and revisit the site until there are no more critical updates.

Install Ad-Aware - Install and download Ad-Aware. You should also scan your computer with program on a regular basis just as you would an antivirus software in conjunction with Spybot.

A tutorial on installing & using this product can be found here:

Using Ad-aware 2007 to remove Spyware, Malware, & Hijackers from Your Computer (http://www.bleepingcomputer.com/forums/?showtutorial=48)

Install Spybot - Search and Destroy - Install and download Spybot - Search and Destroy with its TeaTimer option.

This will provide real-time spyware & hijacker protection on your computer alongside your virus protection. You should also scan your computer with program on a regular basis just as you would an anti virus software. A tutorial on installing & using this product can be found here:

Instructions for Spybot S & D (http://www.bleepingcomputer.com/forums/?showtutorial=43)

Install SpywareBlaster - SpywareBlaster will added a large list of programs and sites into your Internet Explorer settings that will protect you from running and downloading known malicious programs.

A tutorial on installing & using this product can be found here:

Using SpywareBlaster to protect your computer from Spyware and Malware (http://www.bleepingcomputer.com/tutorials/tutorial49.html)

Update all these programs regularly - Make sure you update all the programs I have listed regularly. Without regular updates you WILL NOT be protected when new malicious programs are released.
Follow this list and your potential for being infected again will reduce dramatically.

Here are some additional utilities that will enhance your safety

MVPS Hosts file (http://mvps.org/winhelp2002/hosts.htm) <= The MVPS Hosts file replaces your current HOSTS file with one containing well know ad sites etc. Basically, this prevents your computer from connecting to those sites by redirecting them to 127.0.0.1 which is your local computer
Google Toolbar (http://toolbar.google.com/) <= Get the free google toolbar to help stop pop up windows.
Comodo BOCLEAN (http://www.comodo.com/boclean/boclean.html) <= Stop identity thieves from getting personal information. Instantly detects well over 1,000,000 unique, variant and repack malware in total. And it's free.
Winpatrol (http://www.winpatrol.com/) <= Download and install the free version of Winpatrol. a tutorial for this product is located here:
Using Winpatrol to protect your computer from malicious software (http://www.winpatrol.com/features.html)

Stand Up and Be Counted ---> Malware Complaints (http://www.malwarecomplaints.info/index.php) <--- where you can make difference!

The site offers people who have been (or are) victims of malware the opportunity to document their story and, in that way, launch a complaint against the malware and the makers of the malware.

Also, please read this great article by Tony Klein So How Did I Get Infected In First Place (http://castlecops.com/postlite7736-.html)

Happy surfing and stay clean!
